Effect of Mycorrhizae and Rhizobia Inoculation and Spraying Sorbitol and Microelements on The Growth and Yield of Pea Plants

This field experiment was conducted during winter 2023 at the Al-Buaitha research station of the College of Agriculture, University of Anbar using a randomized complete block design (RCBD) and employing two factors. The first was the addition of biofertilizers (full fertilizer connection, mycorrhizae+½ connection, rhizobia + ½ connection, mycorrhizae+ rhizobia+ ½ fertilizer connection) and the second involved leaching with sorbitol and larger elements and four treatments (no spraying, sugar alcohols, zinc, boron, sugar alcohols + zinc + boron). The results showed that adding biofertilizers (mycorrhizae + rhizobia) led to a significant increase in plant length (113.29 cm), number of branches (8.51 plant branch-1), pod length (9.10 cm), pod weight (7.41 g), number of seeds per pod (6.63 pod seed-1), number of pods (31.87 pod plant-1), plant yield (237.14 g plant-1), hectare yield (12.65 ton ha-1), seed nitrogen content (3.15%), seed phosphorus content (0.422%), seed TSS ratio (14.08%), and seed protein percentage (19.69%). There was also a significant effect from the sorbitol and microelements spraying treatments on plant length (117.70 cm), number of branches (9.35 plant branch-1), pod length (9.63 cm), pod weight (7.60 g), number of seeds per pod (6.99 pod seed-1), number of pods (31.61 pod Plant-1), plant yield (240.27 g plant-1), hectare yield (12.81 t ha-1), seed nitrogen content (3.17%), seed phosphorus content (0.427%), seed TSS ratio (14.36%), and seed protein percentage (19.81%)
